- the beam 42 on which it is wound, there is oppor- The peripheral portions of the disks 34 appear T- shaped in cross-section (Fig. 3) and all have, projecting in a common rotative direction, the hooks 340. (Fig. 6).

Of course, as in the mentioned Mason patent the brush and parting element may have such longitudinal extent as to operate on both warp and weft floats and they will be arranged usually more or less oblique to the path of travel of the fabric so; as to insure catching floats of I both classes; in the present example, where floats occurring at the edge of the fabric are to be parted, said element and brush are shown as having only limited length. Trouble is experienced in the floats or loops caught by the hooks, and supposed thereupon to be parted by the cutter disks, starting to wrap and sometimesactuallywrapping around the element 24 without becoming parted, which of course mars the goods, wherefore the invention includes the: following:

A collar 36 having two arms 37 has clamped to itsarms two blades 38 arranged in a plane substantially tangential to the collar andadjustable toward and from each other to vary the gap between them by having the bolts 39 which clamp them to'the arms penetrating slots 40 in the latter. The collar receives the sleeve 22b of bracket 22 for the parting element and is clamped thereto by the screw 41 so that the blades will lie close to that face of the fabric which is opposed by the parting element. The edge floats are sometimes many inches in length. Since the parting element rotates in such direction that each hook nearest the fabric projects in the direction (arrow y, Fig. 1) in which the fabric is drawn, as'by tunity for any float happening not to be severed to slip off the hook. But in any event when this device is employed, affording as it does only a limited gap receiving the nip formed by the brush and parting element and through which any float caught by a hook will tend to be drawn by the hook, the severing or other parting is usually effected before the float can become appreciably if at all wrapped around the parting element.

While Iprefer that said device should actually forma gap (or include two blades) it will be understood that one blade (as the right-hand blade inFig. 6) forms a float-abutment at that side of 1 the line of closest approximation of the hooks to the'fabric' toward which they project as, in the rotation of said element, they successively depart from the fabric, such loop-abutment of itself producing a pronounced bend in any float or loop starting to wrap around said element, and thus insuring the parting of such float.

I This device also acts as'a guard to prevent the fabric," if suificiently slack, otherwise possibly to be caught by the hooks 34a, and perhaps doirreparabledamage to the cloth. In addition there is thisadvantage; to Wit, that any arching of a loop toward the parting element which the brush tends to effect is of relatively short radius, so that loops that otherwise might pass unparted are with assurance. caught by the hooks, to be thereupon parted.

[The side flanges formed on. the disks 34 as an incident of their T-shaped form are of importance thus: Without such a flange adjoininga cutter 32 it is found that though a loopmay be severed, as in an arc 2 (Fig. 6) sometimes the loop breaks off rotatively back of this point and lodges between the cutter disk and the disk having the hooks, and when such broken-off portions sufficiently accumulate the cutter disk becomes of course ineffective to act. If the flanges are pres ent each act as a guard or fender with respect tothe corresponding cutting edge, appreciably obstructing the entrance of the broken off portion between the cutter disk and adjoining disk 34 so that said portions fall away from the parting element.

Having thus fully described my invention what I claim is:

1. A mechanism of the class described comprising a frame, a coactive rotary brush and float-parting element arranged to peripherally engage the fabric being treated at the opposite faces thereof, and means to support said brush and element on the frame including brackets on which they are journaled and a supporting member for said brackets angularly related to the "axes of said brush and element and around which one bracket is adjustable independently of the float-parting element to peripherally engage the fabric at the opposite faces thereof, means, mounted on the'bar, having bearings for said brush and element, and means to adjust the bar rotatively in each direction comprising screws tapped into the frame and engagingthe bar and respectively arranged to adust the bar around its axis in opposite directions.

3. A mechanism of the class described comprising a frame, a bar therein, said frame having means'to support the fabric in a plane substantially parallel with the bar, a coactive rotary brush and float-parting element adapted to peripherally engage the fabric at opposite faces thereof, supporting means onwhich said brush and element are journaled including a carriage slidable along and splined to the bar and means on the frame for shifting the carriage along. the ban 4. A mechanism of the class described com prising a frame, a bar therein, said frame having means to support the fabric in a plane substan-' slidable along and splined to the bar and' having' a rack extending lengthwise of the U bar, and means to shift the carriage along the bar including a rotary member joumaled in the frame and having a pinion meshing with the rack.

5. A mechanism of the class described comprising a rotary float-parting element having peripheral hooks projecting in one direction around its axis, supporting structure in which said element is journaled having means to support the fabric with one face thereof presented to the periphery of said element, and a float-abutment carried by said structure and extending substantially parallel with the axis of said element and close to said face of the fabric and also close to' that side of the line of nearest approximation of the hooks with the fabric toward which they project as, in the rotation of said element, they successively depart from the fabric.

6. A mechanism of the class described comprising a rotary float-parting element having peripheral hooks projecting in one direction around its axis, supporting structure in which said element is journaled having means to support the fabric with one face thereof presented to the periphery of said element, and means, carried by said structure and arranged close to said face 01' the fabric, forming a gap of limited width extending lengthwise of'the axis of said element and having its sides both sides of the line of nearest approximation of the hooks with the fabric.

'7. A rotary float parting element comprising a substantially circular cutter disk having a pcripheral cutting edgerand a disk coaxial with.

and arranged close to but spaced from the cutter disk and having peripheral hooks all projecting in one rotary direction and crossing the periphery of the cutter disk, the second named diskhaving a side flange on each hook adjoiningthe cutter disk and arranged in a diameter exceeding that of the cutter disk.
